I know that this post will be elementary to those who are mature
Christians here. But for the sake of evangelism, for those who do
not know what the Gospel is, this post is written. May God use it
for the salvation of souls.

What is the Gospel?
There are questions we cant afford to have the wrong answers to.
Questions that our eternities hang on and depend. And one such
question is the one above: What is the gospel?
For sure, you have heard this word gazillion of times already but
what is it? Do you know? First, before going into the answer, let
me catalog for you what the gospel is not:
The Gospel is
.
not the 10 commandments [these only show you
that you need the Gospel. it is not the Gospel]
.not the whole Bible [The OT prophecied about
the Gospel. It is not the Gospel. The NT is the fulfillment of the
Gospel{Matthew to John}. The book of ACTS show us the gospelization
of the apostles. The Books from Romans to Revelation show us the
implication of the Gospel with regards to our moral lives. The NT
is not the Gospel. It contains the Gospel]
.not the whole New Testament
.not All the commandments in the New Testament
[these NT commands were given to those who have already recieved
the Gospel. They are not the Gospel]
..not Prayer [This is what those who have
recieved the Gospel should be doing after they have recieved it.
This is not the Gospel]
..not Matthew, Mark, Luke and John. [these
individual books of the Bible are not the Gospel, they contain the
Gospel]
so what's the Gospel?
The Gospel, dear reader, is the Lord Jesus Christ Himself and what
He did on the cross of Calvary for you and me. The Gospel is the
death and resurrection of the Lord Jesus Christ for the sins of
sinners. Anytime you hear these words:
The Lord Jesus Christ died for the sins of sinners, buried
and resurrected for us."
everytime you hear those words my friend you hear the Gospel, the
Good News of salvation. Youve heard that millions of times already
right? You know what the Bible says about the Gospel? You know
whats the divine commentary of the Bible about the Gospel?
Here read it for yourself:
For I am not ashamed of the gospel of Christ, for it is the power
of God to salvation for everyone who believes, for the Jew first
and also for the Greek.
For in it the righteousness of God is revealed from faith to
faith; as it is written, "The just shall live by faith." [Romans
1:16-17]
The Gospel speaks about Christs humiliation for our exaltation.
From the vantage point of the world, Christs hanging there on the
cross seemed a failure, a picture of defeat. The world laughs and
scorns: whats there in a man nailed to the cross? How can that be
good news for me
this is plain foolishness.
But Paul was not ashamed to proclaim such a message. Why? Because
it is the power of God to salvation for everyone who believes.
The Gospel is the life-boat in a sea where every ship is sinking.
The Gospel is the only strong and formidable tower of salvation
that men and women can take refuge. The Gospel is the Rock of
Gibraltar that stands mighty and indomitable in the midst of
shaking foundations. When the smoke clears, only the truth of the
Gospel will be seen standing firm unscathed.
It is the power of God to salvation it cannot sink; God is its
buoy. It cannot crumble; God is its architect and builder. It
cannot fall; God is its foundation. It is trustworthy; its Gods
saving truth.
Practical Application:
What are you doing with the truth of the Gospel, dear reader? Its
meant to benefit us sinners like you and me.
Are you trusting it?
a)You are not trusting the Gospel [the work of salvation by the
Lord Jesus Christ] if you attempt to be right with God through good
works.
b)You are not trusting the Gospel if you believe that somehow your
good deeds can lessen and atone for your sins.
c)you are not trusting the Gospel if you think that it's your good
works + the Gospel can get you to enter the Kingdom of
heaven.
d) you do not have true faith in the Gospel if you do not reciieve
it with a repentant heart.
He came to die for the sins of sinners and rose again for our
justification [justification-meaning that we may be declared
perfectly righteous in Gods eyes forever]. What you must do is
trust the Good News of salvation.
Here's the Gospel command: Trust in the saving work of Christ on
Calvary alone.
May God bless
you
